Early detection of urological malignancies in Lynch syndrome: a systematic review.
Synthesis in Familial cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Lynch syndrome predisposes to multiple cancer types, including urological malignancies. However, no evidence-based recommendations for surveillance of urological malignancies currently exist. In this systematic review, we aim to describe the current evidence regarding surveillance for these cancers. A systematic literature search was conducted using MEDLINE, searching for urological malignancies, Lynch syndrome, and surveillance including the results of the surveillance methods. Sensitivity and specificity were calculated, when possible, preferably for pooled data from each surveillance method. The risk of bias was assessed using the Newcastle–Ottawa Scale. After full text-screening, nine studies published in 2008–2025 met the inclusion criteria, including two on prostate cancer and seven on urothelial cancer. Prostate cancer-antigen (PSA) surveillance led to 38 prostate cancer diagnoses in 865 individuals with Lynch syndrome, with 71% being clinically significant prostate cancers. In 1564 individuals, 11 urothelial carcinomas were diagnosed by different surveillance methods and 15 diagnoses were missed. Sensitivity of urinalysis, urine cytology, urine MSI, and CT and cystoscopy was 11%, 30%, 100%, and 100% respectively. Specificity was 90%, 97%, 99%, and 100% respectively for these methods. Further data is needed but for prostate cancer surveillance PSA shows promise, while for MSH2 carriers at least, urine microsatellite instability analysis shows promise as a urothelial cancer surveillance test.
